I successfully compiled Johns port for the 18f2550. I just changed
the LEDs to Port C. I flashed it to my test board, but it didn't
work. I figured out that the config words aren't set in the code
(right?) so I added them. Anyway, still no luck. The only thing I
managed was making my USB freeze. I definitely need to take a closer
look at my setup.
Sadly I'll haven't have to much time the next three weeks, gota go to
the army..., but I'll take my laptop. So I'm looking forward to
reading about the results.
Cheers,
Ezra.
